Opis:
On the basis of forest taxation data the presence of European ash in the Bardzkie Mountains area (central part of the Sudety Mountains) was analysed. This included the reckoning of the number of sites and the area covered by ash in various forest habitat types, age classes, altitude zones and on variously slanted and exposed mountain sides. The decline in the number of ashes in younger age classes and complete absence of trees older than 140 years have been noted. In the Bardzkie Mountains ash is the main species forming the forest on mountain riparian forest stands (a 43% participation in the area of forest of this type). Considering the number of specimens most ashes are scattered in mountain broadleaved forest. To the altitude of 650 m ash’ participation in the forest stand composition is stable (30% of analysed locations), but it occupies only 2.6% of total forest area.

Opis:
Elm resources in Poland were analysed on the basis of latest forestry inventory data (updated in 2012). As compared with the 1970s, a remarkable increase was noticed in the total area of forest stands dominated by elms. However, the contribution of elms to the total forest area in Poland is still small (17 653.67 ha, i.e. 0.24% of the total forest area), while forest stands dominated by them cover only 1011.84 hectares (0.01%). Elm forests are the most frequent at alluvial sites, but majority of elm trees is scattered in lowlands, mostly at the fertile potential sites of oak−hornbeam forest. Elms do not prefer any part of Poland, but their contribution is markedly lower in forests of the Sudety Mountains.

Opis:
The research described in this article was conducted in the Tatra National Park in Poland, which is considered as one of the most-visited national parks in Europe. The exceptional popularity of this place is responsible for intensification of morphogenetic processes, resulting in the development of numerous forms of erosion. This article presents the outcomes of the research whose purpose was to verify the usability of unmanned aerial vehicles to check the condition of hiking trails and forests in alpine areas. An octocopter equipped with a non-metric camera was used for measurements. The paper sketches the methodology of data acquisition in harsh conditions and demanding locations of hiking trails on steep Tatra slopes. The paper also describes stages that lead to elaboration of basic photogrammetric products relying on SfM (Structure from Motion) technique. Finally, it shows the applicability of the prepared products to the evaluation of erosion along hiking trails, and to the study of plant succession or tree stand condition in the area located next to hiking trails.
